Compressor system and method of inserting and pulling out bundle of compressor

Abstract

A compressor system includes: a first compressor including a first casing having a cylindrical shape, and a first bundle capable of being inserted into and pulled out from the first casing in an axial direction of the first casing; and a second compressor including a second casing having a cylindrical shape, and a second bundle capable of being inserted into and pulled out from the second casing in an axial direction of the second casing. The first and second compressors are arranged to face each other to cause pullout directions of the respective bundles to be opposite to each other. A maintenance space shareable for insertion and pullout operations of the first bundle and insertion and pullout operations of the second bundle is interposed between the first bundle and the second bundle, and is available for the bundle under the insertion and pullout operations.

What is claimed is: 
     
       1. A compressor system, comprising:
 a first compressor including a first casing having a cylindrical shape, and a first bundle that is capable of being inserted into and pulled out from the first casing in an axial direction of the first casing; and 
 a second compressor including a second casing having a cylindrical shape, and a second bundle that is capable of being inserted into and pulled out from the second casing in an axial direction of the second casing, 
 wherein
 the first compressor and the second compressor are arranged to face each other to cause pullout directions of the respective bundles to be opposite to each other, 
 a maintenance space shareable for insertion and pullout operations of the first bundle and insertion and pullout operations of the second bundle is interposed between the first bundle and the second bundle, and is available for the first bundle or the second bundle under the insertion and pullout operations, and 
 
 the compressor system further comprises rails laid in the maintenance space, the rails being engageable with rollers attached to the first bundle when the first bundle is inserted into and pulled out from the first casing, the rails being engageable with rollers attached to the second bundle when the second bundle is inserted into and pulled out from the second casing. 
 
     
     
       2. The compressor system according to  claim 1 , further comprising:
 a first base portion supporting the first compressor; 
 a second base portion supporting the second compressor; and 
 a maintenance base portion supporting the rails. 
 
     
     
       3. The compressor system according to  claim 1 , wherein a length L of the maintenance space corresponds to a dimension obtained by adding a length L 3  of a work region in front of the first bundle or the second bundle to a length L 1  of the first bundle or a length L 2  of the second bundle. 
     
     
       4. The compressor system according to  claim 1 , wherein a length L of the maintenance space corresponds to a dimension obtained by adding a length L 3  of a work region in front of the first bundle or the second bundle to a larger one of a length L 1  of the first bundle and a length L 2  of the second bundle. 
     
     
       5. The compressor system according to  claim 2 , wherein the maintenance base portion connects the first base portion and the second base portion. 
     
     
       6. The compressor system according to  claim 2 , wherein the maintenance base portion includes a plate that is laid between an end part of the first base portion and an end part of the second base portion. 
     
     
       7. The compressor system according to  claim 6 , wherein the maintenance space is a space on the plate. 
     
     
       8. A method of inserting and pulling out a bundle of a compressor, the method comprising, in a state where a maintenance space shareable for insertion and pullout operations of a bundle of a first compressor having a cylindrical casing and insertion and pullout operations of a bundle of a second compressor having a cylindrical casing is interposed between the bundles and the first compressor and the second compressor are arranged to face each other to cause pullout directions of the respective bundles to be opposite to each other;
 pulling out the bundle of the first compressor or the bundle of the second compressor from the corresponding casing to the maintenance space or inserting the bundle of the first compressor or the bundle of the second compressor into the corresponding casing, while allowing the bundle of the first compressor or the bundle of the second compressor to occupy the maintenance space, 
 wherein rails are laid in the maintenance space, the rails being engageable with rollers attached to the bundle of the first compressor when the bundle of the first compressor is inserted into and pulled out from the casing of the first compressor, the rails being engageable with rollers attached to the bundle of the second compressor when the bundle of the second compressor is inserted into and pulled out from the casing of the second compressor. 
 
     
     
       9. A compressor system, comprising:
 a first compressor including a first casing having a cylindrical shape, and a first bundle that is capable of being inserted into and pulled out from the first casing in an axial direction of the first casing; and 
 a second compressor including a second casing having a cylindrical shape, and a second bundle that is capable of being inserted into and pulled out from the second casing in an axial direction of the second casing, 
 wherein
 the first compressor and the second compressor are arranged to face each other to cause pullout directions of the respective bundles to be opposite to each other, 
 a maintenance space shareable for insertion and pullout operations of the first bundle and insertion and pullout operations of the second bundle is interposed between the first bundle and the second bundle, and is available for the first bundle or the second bundle under the insertion and pullout operations, and 
 a length L of the maintenance space corresponds to a dimension obtained by adding a length L 3  of a work region in front of the first bundle or the second bundle to a length L 1  of the first bundle or a length L 2  of the second bundle.
